31930288 ÷ 689 
Our goal is to divide 31930288 by 689.

Let's proceed to step 1:
When dividing 3 by 689, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 689

Advancing to step 2:
31 divided by 689 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 689

Step 3:
689 can be fit into 319 0 times, resulting in a remainder of 319.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 319 after subtracting 0 from 319.
Bring next digit (3) of the dividend behind the 319 and repeat the process: 3193 / 689

Step 4:
If we divide 3193 by 689, we get 4 and a remainder of 437.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2756 away from 3193, we end up with 437.
Fetch the next digit (0) from the dividend, attach it to 437 and continue: 4370 / 689

Step 5:
689 goes into 4370 6 times with a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
The remainder is 236 after subtracting 4134 from 4370.
Append the next digit (2) from the dividend to 236 and continue with: 2362 / 689

Let's proceed to step 6:
689 can be fit into 2362 3 times, resulting in a remainder of 295.
The next digit of our result is 3. 
Result so far: 463.0
If we take 2067 away from 2362, we end up with 295.
Bring next digit (8) of the dividend behind the 295 and repeat the process: 2958 / 689

Advancing to step 7:
689 can be fit into 2958 4 times, resulting in a remainder of 202.
The number 4 becomes the next digit in our result. 
Result so far: 4634.0
The remainder is 202 after subtracting 2756 from 2958.
Bring next digit (8) of the dividend behind the 202 and repeat the process: 2028 / 689

On to step 8:
When dividing 2028 by 689, we get 2 with a remainder of 650.
The number 2 becomes the next digit in our result. 
Result so far: 46342.0
The remainder is 650 after subtracting 1378 from 2028.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 9:
If we divide 6500 by 689, we get 9 and a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 46342.9
If we take 6201 away from 6500, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 10:
If we divide 2990 by 689, we get 4 and a remainder of 234.
The next digit of our result is 4. 
Result so far: 46342.94
Subtract 2756 from 2990 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 11:
The number 689 fits into 2340 3 times, leaving a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 46342.943
The remainder is 273 after subtracting 2067 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 12:
2730 divided by 689 is 3 with a remainder of 663.
Put 3 as the next digit of the answer. 
Result so far: 46342.9433
If we take 2067 away from 2730, we end up with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

After the division, we end up with 46342.9433 and a remainder of 0.00663.
